## Oracle Database 21c Express Edition on Windows - Pre-Configured AMI

Oracle Database 21c Express Edition (XE) delivers the full power of Oracle's converged database engine with zero licence fees, capped at 2CPU threads,2 GB RAM, and 12 GB user data. This cloudimg AMI packages Oracle XE on Windows Server so you can launch a production-ready Oracle environment in minutes rather than spending hours on manual installation and configuration.

## Why Choose This AMI Over Manual Setup or Alternatives

• Deploy in minutes, not hours - Skip the multi-step Oracle installer, Windows configuration, and AWS agent setup. This AMI is ready to accept connections immediately after boot.
• Pre-installed AWS tooling - AWS CLI v2, Systems Manager Agent, and CloudWatch Agent come configured out of the box, giving you automation, patching, and observability from day one.
• ENA Express optimised networking - Single TCP flow bandwidth up to 25 Gbps accelerates Data Pump exports, RMAN backups, and bulk data transfers to S3.
• Multi-version Windows support - Available on Windows Server 2016, 2019, and 2022 so you can match your organisation's OS standard.
• Average 1-hour support response - cloudimg's 24/7 Oracle specialists respond to tickets in an average of one hour, with a guaranteed 24-hour maximum response time.

## Security and Hardening

• Latest Windows patches applied - The AMI ships with current cumulative updates to minimise the vulnerability window at launch.
• EBS encryption compatible - Launch with encrypted EBS volumes to enable AES-256 encryption at rest for all Oracle data files,redo logs, and backups without additional configuration.
• Windows Firewall active - Only required ports (RDP 3389, Oracle listener 1521) are open by default; all other inbound traffic is blocked.
• Oracle default accounts locked - Non-essential database accounts are locked and expired, reducing the attack surface from first boot.
• Systems Manager for patch management - SSM Agent enables automated patching schedules so your instance stays current without manual intervention.

## Common Use Cases

• Learning SQL and PL/SQL with full Oracle compatibility
• CI/CD pipelines requiring an Oracle instance on demand
• Small departmental applications or ISV products embedding Oracle XE
• Proof-of-concept environments before migrating to Oracle Standard or Enterprise editions
